With the development of small and intelligent wearable electronic devices in recent years, product flexibility will become a development trend. It is said that 2019 is destined to be an extraordinary year, or it can be called the "first year" of folding mobile phones. From Samsung Huawei to OPPO Xiaomi LG Sony Plus Lenovo, today's news, plans to launch their own "collapsible mobile phone" in 2019. Collapsible mobile phones, which are regarded by many manufacturers as the future trend, are "foldable" and "flexible" for wearable devices. Recently, the Wu Zhongshuai team of the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences and the Ren Wencai of the Institute of Metals have teamed up to develop a universal, efficient and industrially suitable method for manufacturing highly integrated graphene-based micro-supercapacitors. This capacitor consists of hundreds to thousands of individual micro-capacitors on any substrate such as a flexible plastic substrate, clothing, glass, A4 paper. This method uses screen printing to quickly and reproducibly produce graphene-based planar micro-supercapacitors, which are manufactured with capacitors of various shapes, aesthetic versatility, outstanding flexibility and superior modules. And other characteristics. The integrated capacitors thus manufactured are flexible, diverse in shape, aesthetically pleasing, and can be bent at will, without any metal connectors, in the future, not only in flexible wearable electronic devices, but also in other future printed electronic products. Has a huge application prospects.
